7.5.2 GPIO Registers

Addr: 05h

GPIO Output

This register controls GPIO outputs.

Description

R/W

R/W

reserved

gpio_out

R/W

Writes a logic signal to pin GPIO; this is independent of any

other bit setting e.g., gpio_mode.

gpi_en

R/W

Enables the GPI input. Set to 1 if used for strobe trigger.

0 = input disabled

1 = input enabled; can be used for strobe trigger

gpi_curr30_en

R/W

Enables the CURR30 input.

0 = input disabled

1 = input enabled

gpi_curr31_en

R/W

Enables the CURR31 input.

0 = input disabled

1 = input enabled

gpi_curr32_en

R/W

Enables the CURR32 input.

0 = input disabled

1 = input enabled

gpi_curr33_en

R/W

Enables the CURR33 input.

0 = input disabled

1 = input enabled

Addr: 06h

gpio_in

N/A

Reads a logic signal from pin GPIO; this is independent of

any other setting e.g., bits Error! Reference source not found..

gpi_in

N/A

Reads a logic signal from pin GPI; if gpi_en=1

curr30_in

N/A

Reads a logic signal from pin CURR31; if gpi_curr31_en=1

curr31_in

N/A

Reads a logic signal from pin CURR31; if gpi_curr31_en=1

curr32_in

N/A

Reads a logic signal from pin CURR32; if gpi_curr32_en=1

curr33_in

N/A

Reads a logic signal from pin CURR33; if gpi_curr33_en=1

Addr: 1Fh

GPIO control

This register controls pins GPIO pin functions.

Description.

1:0

gpio_mode

R/W

Defines the direction for pin GPIO.

00 = Input only; can be used for external PWM

or preview mode

01 = Output (push and pull).

10 = Output (open drain, only push; only NMOS is active).
